Intellitec Just Failed

[Techie]

We're sitting reading, connected to shore power, and all of a sudden the overhead lights go out. FYI -- it had just stopped raining, but it had been raining on/off for several days.
As I check the coach I confirm that we have 120 VAC, the inverter is in stand-by but the EMS display doesn't show anything; and none of the intellitec switches does anything and they are all blank (off).
So, I reset the shore power - inverter comes on as expected - and still nothing on the EMS panel display. Then I turn off the battery power (disconnect switch). After about a minute turn it back on and still nothing on the EMS panel display but almost all of the intellitec switch panels are blinking amber.
Switches are still non-responsive.
In the rear closet I check and the override switches for water pump, 1 front and 1 rear light are working. Take off the panel and can see power to each of 3 circuit boards (red light). I remove & check the 3 AMP fuse on the control board and it's OK.
Any suggestions out there as to what to check for next?

I am not an expert, but on my unit I remove the remote display unit from the wall then unplug the phone line type plug for 20 seconds. When I plug it back in everything is reset and works fine. Not sure about your unit. The other end of the wire is easier to get at in the inverter compartment but I did not try it there yet!

It's not the inverter remote but the intellitec (multiplexed switches for lights)

Well just before bedtime the panels stopped flashing but did not respond. I turned off the overrides and then disconnected battery power for a minute. After powering back up everything came back as normal including the EMS panel. As of this AM everything is still working.
WOuld love to know what to look for in case this ever happens again...very weird!

How many of the lights did you have on? Just wondering if it could be a heat related issue (load) and when things cooled down resumed operation. Have you located the relay controller and looked at the connections on it? I recommend you do so. Loose connections will create heat and deteriorate the wiring and controller connection pins.

Did you reset the two switches in the cloths closet?

I had tried the override (no resets) switches several times as well as had turned off battery power a few times. As I had stated in my last note everytrhing just came back and has been fine since then.

Ref#of lights, just 2 sets -- one of the overhead sets in the front and one of the reading sets in the front.

When things fixed themselves, the front overhead was still on as it is also controlled by the manual override in the closet.

I had taken the panel off in the bedroom closet and all connections had looked secure, no evidence of corroding or mositure and I had removed and checked the 3 amp fuse on the controller as well.

It's now been 3 days since the incident and no repeat.

I have an Allure 470 Coach #31461, 42ft Siskiyou Summit, quad slide.
It has an Intellitec Multiplex Switching System in my coach that
controls all the lights via 8 pannels.
About a year ago all the lights came on and those that are dimmable
started cycling through their dimming cycles also all the "Amber and
Green" lighting in the panels were on and I had no control over any
of the lights or water pump. Interesting expirence at 2AM.
I got all the lights lighs off by using the "House Battery-disconnect
switch. The next day I found that if I disconnected "J2 Power
connector" of the EMS Control Module for 30 seconds the problem was
sort of fixed for a short time then came back. By repeating the
above and removeing all power from the coach for 5 hours it seems to
have fixed everything. No occurances in the past in the past year.
Well last night as we were packing for trip it started again. The rain has stopped my electrical work.
I have calls and emails to CC and Intellitec, but no response from
either. Didn't expect any.
